Azure Cognitive Search is a search-as-a-service cloud solution that gives developers APIs and tools for adding a rich search experience over private, heterogeneous content in web, mobile, and enterprise applications. Azure Cognitive Search allows you to store operation logs and service metrics in an Azure Storage account. This Power BI app enables you to analyze those operation logs and metrics. The app provides detailed insights about your search service, including information about Search, Indexing, Operations, and Service metrics.
